P-565 is a transparent,  two component, addition reaction, platinum catalyzed silicone rubber. It is designed to remain water-clear even after extended exposure to the sun. Although P-565 has very good physical properties for an unfilled system, it is not designed as a mold-making rubber, rather, it is used as the article. 

P-565 was developed to make sculptured articles and for special effects applications that demand clarity. 

Mixing Instructions: Mix 100 Parts by weight of P-565 base with 10 parts by weight P-565 activator in a container that will hold approximately 4 to 5 times the volume being used. Mix thoroughly either by hand or by mechanical mixing After mixing, place the material in a vacuum chamber capable 28 to 29 inches of mercury vacuum. The material will expand to approximately quadruple its original volume and then collapse. Maintain in vacuum for an additional 2 to 3 minutes and then remove.
